b.State University's director of recruitment for the M.B.A. program recently extended offers to 20 promising students. Only five offers were accepted. In the past, acceptance rates averaged 90%.

c.Montgomery Candy Company has enjoyed great success in its small regional market. Management attributes much of this success to Montgomery's unique distribution system, which ensures twice-weekly delivery of fresh products to retail outlets.
